Abstract
Increasing environmental pollutant, especially heavy metals, is due to the industrialization of human societies. Nickel as one of the essential micronutrients in plants is necessary for normal plant growth and development but in high concentrations- As a heavy metal- exhibits toxicity. In this study the effect of different concentrations of Ni (0, 100, 300µM) was studied on germination, growth and some biochemical parameters of echium amouneum under controlled conditions. Based on these results, Ni had no significant effect on germination. In general, there was a decrease in growth parameters such as fresh and dry weights of aerial parts and roots, relative growth rate (RGR).DOI: http://dx.doi.org/10.3126/ijls.v9i2.12060 International Journal of Life Sciences 9 (2) : 2015; 33-38
